The Typical CNC System: FANUC Control System

FANUC control system is a widely used and highly prevalent type of CNC system, and many CNC programming textbooks are explained according to this system. Below is a brief introduction to the functions of the FANUC control system.

FANUC Control System Functions

The FANUC control system is a product of Japan's Fujitsu company. The FANUC control system has a very long history and has various models of products.

FANUCcontrol system extensively uses a modular structure in its design. This structure is easy to assemble and disassemble, the various control boards are highly integrated, greatly improving reliability, and it is also convenient for maintenance and replacement. The FANUC control system has a well-developed self-protection circuit.

The PMC signals and PMC function instructions are extremely rich, making it convenient for tool machine manufacturers to compile PMC control programs, and increasing programming flexibility. The FANUCcontrol system provides a serial RS232C interface, and an Ethernet interface, enabling data transfer between the PC and the machine tool.

The FANUC control system is stable in performance, has a user-friendly interface, and the overall structure of the system series is very similar, with a basically unified operation interface. The FANUC control system can be used in a relatively wide range of environments, with not particularly high demands on external conditions such as voltage and temperature, thus exhibiting strong adaptability.

FANUC Control System Characteristics

Given the above characteristics, the FANUC control system has a wide customer base. The team of operators using this system is very large, so it is necessary to understand some of the software and hardware characteristics of the FANUCcontrol system.

Rigid Tapping

The spindle control circuit uses position closed-loop control, with the rotation of the spindle motor fully synchronized with the tapping axis (Z axis) feed, achieving high-speed and high-precision tapping.

Compound Machining Cycle

The compound machining cycle can generate a series of cutting paths with simple instructions. For example, once the final contour of the workpiece is defined, tool paths for multiple roughing operations can be automatically generated, simplifying lathe programming.

Cylindrical Interpolation

Suitable for cutting slots on a cylinder, programming according to the development drawing of the cylindrical surface.

Direct Dimension Programming

Dimensions such as linear inclination, chamfer values, and corner radius values can be directly specified, as designated on part drawings, simplifying the programming of part machining programs.

Memory-Type Pitch

Error compensation can compensate for mechanical system errors like lead screw pitch errors, with compensation data stored as parameters in the CNC's memory.

CNC Built-In PMC Programming Capabilities

PMC controls the program of the machine and external equipment.

Random Storage Modules

MTP (Machine Tool Manufacturer) can directly change PMC programs and macro actuator programs on the CNC. Since flash memory chips are used, there is no need for a dedicated RAM writer or PMC debugging RAM.

The FANUC control system occupies an important position in modern industrial automation, providing high-precision, reliable control for equipment, capable of accomplishing various complex automation tasks. Whether for CNC machine tools, industrial robots, or automated production lines, the FANUC control system can provide strong support and assurance.
